Setting up the multiple coexistent radio of a globalization system that plans as a whole types of applications certainly will will expend surprising resource, just is enough to finish its development of infrastructure network, and eliminates and change existing number in hundreds of millions running gear.By contrast, develop a kind of can identification arround communication environment situation (for example operational through formal license frequency range/without formal license frequency range, operational network system) and can adopt the running gear of appropriate communication mode in response to user's demand, be comparatively actual and feasible way.
Therefore, conception of the present invention system is considered as multiple modular system in the coexistence of each side such as time, frequency and space with whole communication network.According to the present invention, be allowed to use more widely various operational resources (no matter at time domain or frequency domain) in the multiple coexistent radio system without the less important user of formal license.
See also Fig. 1.Fig. 1 is the schematic diagram of the multiple coexistent radio system 1 of one specific embodiment according to the present invention.As shown in Figure 1, multiple coexistent radio system 1 comprises base station system 10, first kind running gear 12 and the second class running gear 14.Base station system 10 can operate under fixed frequency range and/or on-fixed frequency range.Base station system 10 comprises main base station subsystem 100 and cognitive radio base station subsystem 102, main base station subsystem 100 comprises at least one main base station 1010, and cognitive radio base station subsystem 102 comprises at least one cognitive radio base station 1020.
Illustrate a main base station 1010 and two cognitive radio base stations 1020 among Fig. 1, but not as limit.In other words, the quantity system of main base station 1010 and cognitive radio base station 1020 decides according to practical application.In addition, illustrate two first kind running gears 12 and one second class running gear 14 among Fig. 1 in addition, but not as limit.In other words, the quantity of the first kind running gear 12 and the second class running gear 14 also can be decided according to practical application.In this embodiment, first kind running gear 12 has cognitive radio function, and the second class running gear 14 lies in the general mobile communication device of running under the fixed frequency range.Because first kind running gear 12 has cognitive radio function, first kind running gear 12 can reconfigure (reconfigure) voluntarily, to link with different base station.
In this embodiment, main base station subsystem 100 lies in running under the fixed frequency range.Fixed frequency range can further be divided into operational through the formal license frequency range and without the formal license frequency range.In the formal license frequency range, the user of main base station subsystem 100 can preferentially use this frequency range.In other words, the user without formal license promptly can't disturb or take this frequency range.And in without the formal license frequency range, the running gear that operates under similar frequency bands just must be shared this frequency range compatiblely.In other words, a plurality of running gears that operate under without the formal license frequency range must exist under the rule of having formulated jointly.In addition, some system as radar system (radar system), must have the right to use of elder generation than other system.
On the other hand, cognitive radio base station 1020 lies under the on-fixed frequency range and operates.Cognitive radio base station 1020 is dynamically to use the available frequency band that can not disturbed by the main base station subsystem 100 through formal license, perhaps shares without the formal license frequency range with other system.In the cognitive radio framework, cognitive radio base station 1020 can have a large amount of internal memories, powerful operation capacity and unrestricted energy and supply with.Cognitive radio base station 1020 can provide the 1st running gear 12 gateways (gateway) function, with access backbone network (backbone network), as internet (Internet).In addition, a plurality of cognitive radio base stations 1020 also can form a meshed wireless backbone network (mesh wireless backbonenetwork), when some cognitive radio base station 1020 and wired backbone network link, can be used as gateway or router (router).Moreover, if the second class running gear 14 is compatible with cognitive radio base station 1020, but also access cognitive radio base station 1020 of the second class running gear 14 then.
Below cooperate Fig. 1 that several communication link relations of the present invention are described.
Communication link A: first kind running gear links first kind running gear
Because first kind running gear 12 has cognitive radio function, but first kind running gear 12 sensings are about one group of information of a communication environment.Then, first kind running gear can be analyzed this group information, and reconfigures (sefl-reconfiguration) voluntarily, to carry out communication by communication link A and another first kind running gear 12.For example, two first kind running gears 12 among Fig. 1 can cooperatively interact the frequency range that can use of ground sensing, wherein this available frequency range can be through the formal license frequency range or without the formal license frequency range.Afterwards, first kind running gear 12 utilizes the frequency range of this available frequency range as its running again.It should be noted that two 12 of first kind running gears can adopt a control channel (controlchannel) of sharing, in order to mutual exchange spectrum information.
It should be noted that, sensing comprises the one or more actions that are selected from the following group about this group information of this communication environment: a frequency spectrum of this communication environment of sensing, one transformat of this communication environment of sensing, a frequency spectrum of sharing this communication environment, and the geographical position of discerning other first kind running gear 12.
In addition, this group information comprise be selected from following group at least one of them: a carrier frequency of the less radio-frequency signal of this communication environment (carrier frequency), one frequency range utilance of this communication environment, one of the less radio-frequency signal of this communication environment receives signal strength pointer (received signal strengthindication, RSSI), and a signal of the less radio-frequency signal of this communication environment to interference-to-noise ratio (signal-to-interference and noise ratio, SINR).
Moreover, first kind running gear 12 is that the one or more actions that are selected from the following group by execution reconfigure voluntarily: the radio frequency of dynamically selecting a running usefulness, selection is applicable to a suitable modulation kenel of a particular transport system, and controls a through-put power dynamically to switch in several transmit power level.
Communication link B: first kind running gear-binding cognitive radio base station
But cognitive radio base station 1020 sensings are analyzed this group information, and are reconfigured voluntarily about this group information of communication environment, to carry out communication by communication link B and first kind running gear 12.For example, cognitive radio base station 1020 is sensing available frequency range around it dynamically, and provides first kind running gear 12 a single access that jump (one-hop access) in its covering scope.May need the detection technology that can cooperatively interact at this.Via cognitive radio base station 1020, first kind running gear 12 gets final product the access backbone network or carries out communication with other base station.
As for cognitive radio base station 1020 how sensing should group information, the content that how to reconfigure voluntarily and should group information be comprised, roughly be as mentioned above, do not repeat them here.
Communication link C: first kind running gear links main base station subsystem
If first kind running gear 12 need be linked to main base station 1010, first kind running gear 12 will reconfigure voluntarily, changes the role identical with the second class running gear 14 into, and carries out communication by communication link C with main base station 1010.In other words, first kind running gear 12 can be reconfigured for the general mobile communication device that operates down in fixed frequency range voluntarily.

But cognitive radio base station 1020 sensings are analyzed this group information, and are reconfigured voluntarily about this group information of communication environment, to carry out communication by communication link D and another cognitive radio base station 1020.Since can directly carry out wireless link between a plurality of cognitive radio base stations 1020, a plurality of cognitive radio base stations 1020 just can form a meshed wireless backbone network.Based on cognitive radio function, a plurality of cognitive radio base stations 1020 are dynamically selected the running frequency range and are carried out communication mutually.Because cognitive radio base station 1020 is very powerful, will be very huge at the binding capacity of 1020 of a plurality of cognitive radio base stations.Therefore under some environment, it is inconvenient desiring in wired mode cognitive radio base station 1020 to be set, and above-mentioned wireless link mode still can reduce cost is set.
Communication link E: the main base station subsystem of second class running gear-binding
This is a known single mode of connection that jumps.The second class running gear 14 is to carry out communication by communication link E with main base station subsystem 100.It is interior as the usefulness of coordinating communication that main base station 1010 ties up to its scope that contains, and provide the second class running gear 14 backbone network access facilities.
Communication link F: second class running gear-binding first kind running gear
In order to communicate with each other between different systems, this kind mode of connection truly has its necessity.In this embodiment, first kind running gear 12 can reconfigure voluntarily, directly to carry out communication by the communication link F and the second class running gear 14.Certainly, first kind running gear 12 also can carry out communication via the base station system and the second class running gear 14.
Communication link G: second class running gear-binding cognitive radio base station
In order to communicate with each other between different systems, this kind mode of connection truly has its necessity.If cognitive radio base station 1020 can with the second class running gear, 14 compatibilities, cognitive radio base station 1020 can carry out communication by the communication link G and the second class running gear 14.By this, cognitive radio base station 1020 can provide the second class running gear 14 access service.
The present invention can be used in network center (network-centric), distributed network (distributed network), peer to peer network (ad hocnetwork) and mesh network about cognitive radio system framework system, and the cognitive radio system framework can provide service to through formal license and/or without the related application of formal license, illustrates as follows now.
Infrastructure network pattern (infrastructure network mode)
See also Fig. 2.Fig. 2 is applied in the schematic diagram of infrastructure network 3 for the present invention.As shown in Figure 2, all there are a single binding that jumps in 1020 of each first kind running gear 12 and cognitive radio base stations.Cognitive radio base station 1020 can be as the usefulness of coordinating communication in the scope that it is contained.
Peer to peer network pattern (ad hoc network mode)
See also Fig. 3.Fig. 3 is applied in the schematic diagram of peer to peer network 4 for the present invention.As shown in Figure 3, there is not any base apparatus in this pattern, as base station.If a first kind running gear 12 has other first kind running gear 12 that can link (connectable) near identifying it, then these first kind running gears 12 can form a peer to peer network.It should be noted that above-mentioned ＂ can link ＂ one speech and be meant that any two first kind running gears 12 can find sharable frequency range, and not disturbing this frequency range under user's situation of formal license, carries out communication mutually.
Mesh network pattern (mesh network mode)
See also Fig. 4.Fig. 4 is applied in the schematic diagram of mesh network 5 for the present invention.As shown in Figure 4, in this pattern, if 1020 of first kind running gear 12 and cognitive radio base stations in covering scope each other, then all first kind running gears 12 and cognitive radio base station 1020 are all and can link.Especially, these fixing cognitive radio base stations 1020 can form a meshed wireless backbone network, and some cognitive radio base station 1020 can be linked to wired backbone network 6, as the internet.Because cognitive radio base station 1020 in use can not need be linked to wired backbone network, so it is provided with the place and has elasticity.
See also Fig. 5.Fig. 5 is for integrating the schematic diagram of peer to peer network and IP mobile management according to the present invention.Between base station and running gear, only there be single jumping a little in wireless telecommunication system under the tradition architecture usually.There is no other between running gear and link path or the multiple point (multi-hop) that jumps.Because all running gears all directly are linked to base station, centralized mobile management scheme is feasible.
For example, for action IP (mobile IP), all cognitive radio base stations 1020 all can be directly to first kind running gear 12 issue Care-of Address (Care-of-Address, CoA).For a first kind running gear 12, obtain a Care-of Address and temporary (home agent, HA) (not shown) are easy to reach to Local proxy server with it from telecommunication network (foreign network).As shown in Figure 5, first kind running gear 12 can link one or more wireless systems simultaneously, and obtain a Care-of Address from each wireless system, perhaps first kind running gear 12 also can be obtained a Care-of Address from each wireless system via cognitive radio base station 1020 or another first kind running gear 12.Afterwards, this Local proxy server (not shown) can be sent to package the Care-of Address of this first kind running gear 12.Illustrate three telecommunication networks 70 and three remote agent devices 72 among Fig. 5, but not as limit, actual quantity is decided by practical application.As under the network architecture of cognitive radio, first kind running gear 12 can side by side be linked to one or more different wireless systems, and obtain a Care-of Address from each wireless system, to arrange the transmitting-receiving path of package, wherein each wireless system belongs to different telecommunication networks respectively.Therefore, to handle multiple Care-of Address be essential to the new scheme of development.Especially, first kind running gear 12 can be obtained Care-of Address from each telecommunication network 70, makes first kind running gear 12 will can not use single Care-of Address to represent its current position and the transmitting-receiving path of arranging package.
In addition, as shown in Figure 5, a plurality of first kind running gears 12 can form a peer to peer network, and some first kind running gear 12 can be linked to cognitive radio base station 1020, with access telecommunication network 70.And these first kind running gears 12 direct and that cognitive radio base station 1020 links promptly are called gateway node (gateway node).Be subject to the covering scope of cognitive radio base station 1020, some first kind running gear 12 also can't directly be obtained Care-of Address from cognitive radio base station 1020.These outer first kind running gears 12 of covering scope that are positioned at cognitive radio base station 1020 can see through above-mentioned gateway node and obtain Care-of Address, to carry out the arrangement in packet receiving and transmission path.
Moreover because a multiple feature that jumps of cognitive radio, the problem of management of signal handover (handover) will not only be present between the single running gear and telecommunication network, also further be present between a plurality of running gears and a plurality of telecommunication network.For example, if some gateway node leaves from the covering scope of cognitive radio base station 1020, these gateway nodes will notify other node in peer to peer network to be about to lose binding.At this moment, if other node in peer to peer network has effective binding, promptly can prepare to carry out the signal handover.
